Georgia Democrat Jon Ossoff is picking up yet another endorsement from a national liberal group in the race for the state’s 6th District.

Democracy for America, a political action committee founded by former Democratic National Committee Chairman Howard Dean, is backing Ossoff, according to a statement obtained first by Roll Call. It’s the group’s first congressional endorsement of the 2018 cycle.

Ossoff, a former Hill aide, has received national attention from Democrats and liberal activists who see an opportunity to pick up a traditionally Republican seat in what is expected to be the first competitive congressional election of Donald Trump’s presidency.

“Electing Jon Ossoff isn’t just an opportunity for Georgia to reject Donald Trump’s hate-fueled agenda, it’s a chance to send a progressive leader from a new generation to Congress to fight for racial justice and against rapidly growing income inequality,” Jim Dean, chairman of Democracy for America, said in a statement.

Ossoff has already been endorsed by End Citizens United, and has received fundraising help from the liberal site Daily Kos. The Democratic Congressional Campaign Committee is sending staff to the district to boost Ossoff, who’s one of five Democrats running in an 18-candidate jungle primary on April 18. If none of the candidates receive more than 50 percent of the vote, the top two vote-getters will advance to a runoff on June 20.

Democracy for America’s approach is rooted in Dean’s 50-state strategy: the idea that liberal candidates should be running across the country, even in red states. The group has about 30,000 members in Georgia and over the 2016 cycle, it raised and spent $2.69 million for candidates running at various levels across the country.

But winning here would still be an uphill climb for a liberal Democrat in a district where Trump underperformed but one that has nonetheless traditionally voted Republican. Health and Human Services Secretary Tom Price, who represented this suburban Atlanta seat for six terms, won re-election last fall by 23 points. Trump, by contrast, carried the district by less than 2 points.

Republicans signaled this week that they’re not taking the race for granted. On Thursday, the Congressional Leadership Fund, a super PAC tied to House GOP leadership, launched a $1.1 million ad campaign attacking Ossoff as inexperienced and dishonest.
